NAME
       Digest::file - Calculate digests of files

SYNOPSIS
	 # Poor mans "md5sum" command
	 use Digest::file qw(digest_file_hex);
	 for (@ARGV) {
	     print digest_file_hex($_, "MD5"), "  $_
";
	 }

DESCRIPTION
       This module provide 3 convenience functions to calculate the digest of files.  The following functions are provided:

       digest_file( $file, $algorithm, [$arg,...] )
	   This function will calculate and return the binary digest of the bytes of the given file.  The function will croak if it fails to open
	   or read the file.

	   The $algorithm is a string like "MD2", "MD5", "SHA-1", "SHA-512".  Additional arguments are passed to the constructor for the
	   implementation of the given algorithm.

       digest_file_hex( $file, $algorithm, [$arg,...] )
	   Same as digest_file(), but return the digest in hex form.

       digest_file_base64( $file, $algorithm, [$arg,...] )
	   Same as digest_file(), but return the digest as a base64 encoded string.
